The Westinghouse J30 was a turbojet engine developed by
Westinghouse Electric Corporation. It was the first American-designed
turbojet to run, and only the second axial-flow turbojet to run outside
of Germany. A simple and robust unit with six-stage
compressor, annular combustor, and single-stage turbine, it initially
gave 1,200 pounds of thrust. Its first flight was under a FG Corsair in
January 1944. It was developed into the smaller J32, and the successful
Westinghouse J34, an enlarged version which produced 3,000 pounds of
thrust.

Developed by
Westinghouse Electric Corp. in the late 1940s, the J34 engine was an enlarged
version of the earlier Westinghouse J30. The J34 produced at least 3,000
pounds of thrust (depending on engine series) and was twice as powerful as its
predecessor.

Several different series J34s were used in Air Force experimental aircraft
during the 1948-1953 period. A J34-WE-22, rated at 3,000 pounds thrust,
powered the tiny McDonnell XF-85 Goblin. The McDonnell XF-88A used two
J34-WE-15 engines, each rated at 3,150 pounds thrust, while the XF-88B used
two XJ34-WE-19s, each rated at 3,250 pounds thrust. Power for the Douglas X-3
Stiletto was provided by two XJ34-WE-17s of 3,370 pounds thrust each. The 15,
17 and 19 engines were fitted with an afterburner for additional thrust when
needed. The engine on display, cut away to reveal internal components, is
representative of the basic J34 type engine.
